Abstract: Now a day’s harmonics are a serious problem in power systems. Due to non-linear loads being added to electrical systems harmonics are generated, which causes the system equipment damage. For improvement of power quality, we are using DFIG with active filters. Doubly Fed Induction Generator for Wind Energy Conversion Systems deals with the operation of doubly fed induction generator (DFIG) with an integrated active filter capabilities using the grid-side converter (GSC). The main contribution of this work lies in the control of GSC for supplying harmonics in addition to its slip power transfer. The rotor-side converter (RSC) is used for attaining maximum power extraction and to supply required reactive power to DFIG. Wind energy conversion system (WECS) works as a static compensator (STATCOM) for supplying harmonics even when the wind turbine is in the shutdown condition. Control algorithms of both GSC and RSC are presented in detail. Implemented project DFIG-based WECS are simulated using MATLAB/Simulink.
